Pure Storage Certified FlashArray Implementation Specialist FlashArray-Implementation-Specialist Prüfungsfragen mit Lösungen (Q60-Q65):

60. Frage
After upgrading Purity during a new installation, which command should an Implementation Engineer run to determine what version of Purity will be loaded at the next boot of the FlashArray?

A. pureversion -a
B. pureboot list
C. purearray list --controller

Antwort: B

Begründung:
The command pureboot list is the correct tool to verify which Purity version is designated to load upon the next system reboot.
FlashArray controllers maintain two boot partitions (often referred to as banks) for redundancy and upgrade safety. When an upgrade is performed, the new Purity software image is written to the inactive bank.
* Verification: Running pureboot list displays the status of both boot banks (e.g., Primary and Secondary) and explicitly flags which version is "Running" and which is set for "Next Boot."
* Why it's critical: Just checking the currently running version (using pureversion or purearray list) is insufficient during an upgrade workflow. An engineer must confirm that the boot pointer has successfully switched to the new version before issuing the reboot command. If pureboot list shows the old version as "Next Boot," a reboot would simply reload the current code, indicating the upgrade installation failed or wasn't finalized.

61. Frage
A FlashArray arrives with Purity 5.3.8 applied out of the factory. The account team requests that the array configured with Purity 6.1.21. Which steps should the Implementation Engineer select to meet this requirement?

A. Copy the PPKG and SHA1 files to a USB stick and upgrade the controllers.
B. Create a bootable USB stick from the 6.1.21 ISO file and reimage both controllers with it.
C. Configure the array with the current code and then open a case with Support to upgrade.

Antwort: B

Begründung:
To upgrade from Purity 5.3.8 to 6.1.21 on a new array, the Implementation Engineer should create a bootable USB installer from the target ISO and reimage both controllers to ensure a clean and supported upgrade.

62. Frage
An Implementation Engineer is onsite to add a new 91TB (10 x 9.1TB) data pack to a FlashArray that includes a DirectFlash Shelf. The chassis currently contains two write groups, one 45TB (10 x 4.5TB) and one
91TB (10 x 9.1TB). The shelf contains a single 45TB (10 x 4.5TB) write group. The customer requests that the new data pack be added as part of a wide write group. How should the Implementation Engineer meet this request?

A. Add the drives to the shelf and then run puredrive admit --wide-write-group to admit them into the same write group in the shelf.
B. Have support set a tunable to allow the wide write group to extend between the chassis and shelf; then add the drives to the shelf to extend the write group from the chassis.
C. Move the chassis write group of 45TB (10x4.5TB) to the shelf and then add the new data pack to the chassis.

Antwort: C

Begründung:
FlashArray performance and capacity management rely on "Write Groups"-logical groupings of drives that Purity uses to stripe data. A "Wide Write Group" typically consists of roughly 20 drives and offers better performance and capacity efficiency than smaller groups. However, Purity generally requires write groups to be contained within a single physical enclosure (chassis or shelf) to maintain failure domain boundaries and performance predictability.
In this scenario, the customer wants the new 91TB pack to form a wide write group. The chassis already has a
91TB group and a 45TB group. The shelf has one 45TB group. To create a wide write group with the new
91TB pack, it is best to pair it with an existing matching or compatible group in the same enclosure. Since the chassis is full (20 drives), you cannot simply add the new pack there without moving something.
The correct procedure is to move the 45TB write group from the chassis to the shelf . This frees up 10 slots in the chassis. The shelf now holds two 45TB groups (which is valid). The chassis now has the original 91TB group and 10 empty slots. The engineer can then install the new 91TB data pack into those empty chassis slots. Purity will then be able to merge or manage these two 91TB packs (the existing one and the new one) as a highly efficient configuration, potentially forming the requested wide write group or at least balancing the high-capacity drives within the controller chassis where bandwidth is highest. This physical rearrangement is necessary because write groups cannot span across the chassis-shelf interconnect.

63. Frage
How many chassis capacity drive slots come standard on a FlashArray//X Gen 2 chassis?

A. 28 slots
B. 20 slots
C. 24 slots
D. 40 slots

Antwort: B

Begründung:
Understanding the physical chassis layout of the Pure Storage FlashArray is essential for capacity planning and hardware installation. The FlashArray//X Gen 2 (and Gen 3) utilizes a highly efficient 3U chassis design.
When looking at the front of a standard //X chassis, there are a total of 24 physical module bays. However, these bays serve fundamentally different architectural purposes:
* Capacity Drive Slots: There are exactly 20 slots strictly dedicated to capacity drives (DirectFlash Modules, or DFMs). These are numbered 0 through 19 and are where the data packs are installed to provide raw storage capacity.
* NVRAM Slots: The remaining 4 slots, located centrally in the chassis, are dedicated exclusively to NVRAM modules (NVB0, NVB1, NVB2, and NVB3). These provide the highly available, non-volatile write cache for the array and cannot be used for capacity expansion.
Therefore, when an Implementation Engineer is assessing the chassis for data pack expansion or module upgrades, there are exactly 20 standard capacity drive slots available before an external DirectFlash Shelf (DFS) must be added. (Note: FlashArray//XL utilizes a larger 5U chassis with 40 capacity slots, but the standard //X remains at 20).

64. Frage
A customer would like to consolidate their SAS shelves and wants to evacuate multiple shelves in parallel. What is a prerequisite for this procedure?

A. The array usage percentage must be lower than 60%
B. Purity must be upgraded to 6.x
C. The array chassis must be fully populated with modules.

Antwort: A

Begründung:
To evacuate multiple shelves in parallel safely during consolidation, the array's usage must be sufficiently low (under 60%) to ensure enough free capacity for data movement.
